         10 . The apparatus of  claim 7 , wherein the pressure monitoring system is coupled to the sound device, and wherein the pressure monitoring system produces a first error signal which may be used to alter the sound produced by the sound device. 
     
     
         11 . The apparatus of  claim 9 , wherein the color of light changes from green to red when the first error signal indicates an error. 
     
     
         12 . The apparatus of  claim 1 , further comprising:
 a flow source; and,   a flow generator coupled to the flow source and the resuscitation control circuit.   
     
     
         13 . The apparatus of  claim 1 , wherein the resuscitation assembly further comprises:
 at least one ventilation line; and,   a resuscitation mask coupled to the at least one ventilation line.   
     
     
         14 . The apparatus of  claim 1 , wherein the resuscitation assembly further comprises:
 at least one ventilation line; and,   a hand-held resuscitation device coupled to the at least one ventilation line.   
     
     
         15 . The apparatus of  claim 14 , wherein the hand-held resuscitation device further comprises:
 an ergonomic handle;   a mouth and nose piece;   a control pad; and,   a display screen.   
     
     
         16 . The apparatus of  claim 14 , wherein the resuscitation assembly further comprises a resuscitation base station which may be coupled to the hand-held resuscitation device. 
     
     
         17 . The apparatus of  claim 14 , wherein the resuscitation assembly further comprises a manual breath trigger for controlling an automatically-timed breathing cycle. 
     
     
         18 . The apparatus of  claim 15 , wherein the mouth and nose piece comprises:
 a mouthpiece; and,   a manifold including at least one nasal prong.   
     
     
         19 . An apparatus comprising:
 a resuscitation control circuit;   a light device; and,   a sound device;   wherein the resuscitation control circuit receives first and second control signals, and outputs a third control signal for activating or deactivating the light device.   
     
     
         20 . The apparatus of  claim 19 , wherein activation of the light device indicates an inspiration period of a resuscitation procedure, and deactivation of the light device indicates an expiration period of a resuscitation procedure. 
     
     
         21 . The apparatus of  claim 19 , further comprising a pressure monitoring system for measuring the airway pressure of a patient.
